BAKING-ovEN.

Specicaton of Letters Patent. Patented May 13, 1919.

Application filed July 9, 1918. Serial No. 244,087.

To aZZ 'whom t may concern:

Be it known that I, MILTON FEDER, citizen of the United States, residingat Oakland, in the county of Alameda and State of California, haveinvented certain new and useful Improvements in Bakin -Ovens, ofi

ywhich the following is a speci cation.

'Ihe invention relates to an improved baking oven, and has for itsobject to provide an oven of simple construction which will be moreefficient in operation and produce better results in baking than ovensheretofore made.

'Ihe invention is illustrated in the accompanyingdrawings which form apart of this specification and the appended claims.

Referring to the drawings:

Figure 1 is a front elevation of the oven with the oven casing swungpartly open.

Fig. 2 is an end elevation of the oven.

Fig. 3 is a cross sectional view of one of the reel bearings.

Fig. 4 is a cross section of the oven taken in a plane corresponding tothe line 4-4 of Fig. 1, but showing the upper casing` close y In thedrawing, 1 indicates' a frame formed with two legs 2 which rest upon theHoor and support the oven. The oven includes a closure 3 which ispreferably cylindrical in form and 'mounted horizontally on said frame.The closure is made with a lower semi-cylindrical section" 4 which isfixed on frame 1 and an upper semi-cylindrical section 5 pivoted in therear at 6 to said lower section, the line of separation of said sectionsbeing substantially coincident with the horizontal diameter of theclosure.A

section at 8 to swing down into its open position. Latches'9 areprovided for holding the door 7 closed. A handle 10 is secured to thedoor 7 for lifting the forward part of the section 5 and swinging itupward and backward on pivot 6, and for opening the door. Stays 11 arepivoted at their upper ends to the ends of the section 5 at 12 and areprovided with notches 13 to receive pins 14 in the ends of the section 4whereby the section 5 is held in partly open position. On a shaft 15extending centrally and horizontally of the closure 3 and journaled inanti-friction roller bearings 16 on the frame 1, is secured a circuitousseries of means for supporting articles to be baked, preferably in theform of a reel 17. Shelves 18 are pivotally suspended on the reel 17longitudinally of the reel to receive the baking pans 19, and to swingand suspend vertically on their pivots as the reel is ro,- tated. Thesection 4 is provided with a longitudinal slot 20 in the bottom thereofdirectly under which is located a burner 21 mounted onthe frame 1. Agear 22 is slidably keyed on shaft 15 to mesh with va pinion 23journaled on the frame 1 which also meshes with a gear 24 journaled onthe frame. A shaft 25 is journaled in bearings 26 on the frame 1, onwhich shaft is secured a worm 27 which meshes with the gear 24. A pulley28 is secured on the end of shaft 25 over which extends a belt 29, whichbelt also extends over pulley 30 of a motorY 31.

Normally 'the reel 17 is' rotated by the motor 3l through the medium ofpulley 30, belt 29, pulley 28, shaft 25, worm 27, gear 24, pinion 23 andsections are partially separated by the stays 11, the reel still entersthe upper concave section, and if traversing of the reel be continued atsuch time the cooling of the bake may be more gradual'if desired.

A glass window 40 is provided in the front of the oven closure throughwhich the baker may observe the bread in the baking pans 19. Bread isvery easily burned in gear 22. The reel however may be disconnected fromthe motor other ovens by the heat remaining in the I ovens after theheat is turned oif, no means being provided for discharging theremaining heat in the oven. My oven however may be opened wide byswinging open the closure section 5 so that the remalning heat in theovenl will readily escape and avoid burning the' bread.

The roller bearings prevent vibration of the reel and falling of thebread, which takes place in other ovens when the oil is dried out in thebearings by the heat,

. of the oven in the lower part thereof andi Batlle plates 50 extendfromend to end vertically through'the slot 20, providing gas outlet passages51 between the plates and the wall of the,J 4oven and the sides of saldslot.

Having described my invention, I claim as y new and desire to secure byLetters Patent:

1. A bakery oven including an oven closure having a lower section' andan upper section, the latter being pivotally connected to the formerwhereby the closure may be opened, and said oven having a circuitousseries of means for supporting articles to be baked, extending into bothsections of the oven closure.

2. A bakery oven including an oven elosure having a lower section and anupper section, the latter being pivotally connected to the formerwhereby the closure may be opened, and a reel rotatively mounted in thelower section for receiving material to be from the walls thereof, andmeans for supplying heat to said closure at the bottom thereof.

il. A baking oven comprising a closure divided horizontally into upperand lower sections, having a circuitous series of traveling bakingsupports mounted in said closure and having means for traversing themtherein; said sections being vertically separable to develop a pair ofopposed concaves with a laterally presented cooling opening between themand the path of the traveling baking supports extending into thecavities of the sections when the latter are so separated.

5. A baking oven comprising a closure divided horizontally into upperand lower sections and a circuitous series of traveling baking supportsmounted in said closule and having means for traversing them therein;said sections being hinged together along one side to render themYvertically separable by swinging movement. to develop a pair ot opposedconcaves with a laterally presented graduated cooling opening betweenthem; the path of the traveling baking supports extending into thecavities of both sections when the latter are soiseparated.

6. A baking oven comprising ya closure divided horizontally into upperand lower sections and having a circuitous series of traveling bakingsupports mounted therein with means for traversing the same; saidsections being hinged together along o'ne side to render them verticallyseparable by swing- Aing movement and having means for defining alimited separation of their three sides and thereby developing a pair ofopposed concaves with a laterally presented graduated cooling openingbetween them; the path of the traveling baking supports extending intoand the traversing means being adapted to cause them to move through thecavities of both sections when the latter are so separated.

7. A baking oven comprising a closure divided horizontally into upperand lower sections, having a eircuitous series ot traveling bakingsupports mounted in said closure and having means for traversing themtherein; said sections being vertically separable to develop a pair ofopposed conca'vcs with laterally presented cooling openingbetween themthe path of the traveling baking snpports extending into the cavities ofthe scctions when the latter are so separated and the free wall of oneof the sections being provided with a door to increase the opening intothe space between the sections.

8. A baking oven comprising a closure divided horizontally into upperand lower sections, having a circuitous series of traveling bakingsupports mounted in said closure and having means for traversing themtherein; said sections being vertically separable to develop a pair ofopposed concaves with laterally presented cooling opening between them;the path of the traveling baking supports extending into the cavities otthe sections when the latter are so separated and the free wall of oneof the sections 4being provided with a door to increase the opening intothe space between the, sectionsl and affording means through which tomanipulate the section which carries it in developing verticalseparation between the sections.

9. A bakery oven comprising a cylindrical closure mounted with its axishorizontal and divided diametrically into upper and lower sectionshinged together along one side of the cylindrical wall and leaving freeseparable edges on the other side thereof; a circuitous series ot'traveling supports for articles to be baked having their path of travelextending through both sections: the upper section having a door hingednear its free upwardly swingingedge and swinging outwardly from saidsections.

ln testimony whereof l alix my signature.

MILTON FEDER.
